DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

This disclosure of this application is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

The terms “a”, “an”, and “the” as used in the claims herein are used in conformance with long-standing claim drafting practice and not in a limiting way. Unless specifically set forth herein, the terms “a”, “an”, and “the” are not limited to one of such elements, but instead mean “at least one”.

Referring to FIGS. 1-3, an overview of an exemplary exercise method is illustrated using an exemplary exercise system 10 that includes a support device or anchor 12 and an exercise device 14. Throughout this document, various different support devices and various different exercise devices are described to establish various different exercise systems.

Referring to FIG. 1, the exemplary support device 12 is an upper body support that includes in one example, at least a stationary bar extending generally horizontally to be held by at least one hand 16 of an individual 18. The exemplary support device 12 is an elongated cylindrical structure sized to be easily gripped by the hands 16. The exemplary support device 12 has a diameter ranging from about 0.5 inch to about 4.0 inches and any diametric value between 0.5 to 4 inches having incrementally differences of 0.01. The support device 12 is supported at opposite ends by a structure not shown in this figure. It should be understood that this exemplary support device 12 is but one non-limiting example and any one of the other various different support devices described throughout this document can replace, or be used in combination with, this support device 12 in an exemplary different exercise system.

Still referring to FIG. 1, the exemplary exercise device 14 supports the lower body of the individual 18. In one example for the exercise device 14 includes a planar structure 20 having opposite sides. A first side of the exercise device 14 receives and secures feet 22 of individual 18 to the exercise device 14. The second side opposite the first side of the exercise device 14 is configured to allow the exercise device 14 to move over a substrate 24. In this exemplary embodiment, wheels or rollers 26 are secured to the second side of the planar structure 20 of the exercise device 14 and provide the movement capability of the exercise device over substrate 24. It should be understood that this exemplary exercise device 14 is but one non-limiting example and any one of the other various different exercise device 14 described throughout this document can replace, or be used in combination with, this exercise device 14 in an exemplary different exercise system.

Referring to FIG. 2, the exemplary method of using the exemplary exercise system 10 includes the individual 18 moving the lower portion of the individual's body 18 via the exercise device 14 over substrate 24 while generally maintaining the upper portion of the individual's body 18 stationary and generally in the same position relative the support device 12. That is, individual 18 is moving the exercise device 14 for a distance 28 from directly beneath the individual's 18 shoulders over substrate 24.

Referring to FIG. 3, the exemplary method of using the exemplary exercise system 10 further includes the individual 18 moving the lower portion of the individual's body 18 for a greater distance 30 from directly beneath the individual's 18 shoulders than distance 28 represented in FIG. 2. As the lower portion of the individual's body 18 moves for a greater distance from directly beneath the individual's 18 shoulders, stress in the joints and tissue of the lower leg area 17 (FIGS. 2-3), including the knees and ankles, increases to compensate for the greater angle of the body from the vertical orientation of FIG. 1.

Referring to FIG. 4, an exemplary support device or anchor 50 is illustrated that includes a pair of vertical poles 52 and 54 extending vertically from a substrate 56. Each vertical pole 52 and 54 can be secured in an opening (not shown) in substrate 56. Additionally or alternatively, each vertical pole 52 and 54 can be supported upon or over substrate 56 with a stand (not shown). An exemplary stand would be a conical structure having large base resting upon substrate 56 and a central opening to receive the bottom end of a vertical pole. Each vertical pole 52 and 54 includes a plurality of openings 58 that are spaced vertically generally along at least a portion of the length of each vertical pole 52 and 54. Each opening 58 in vertical pole 52 has a corresponding opening 58 in vertical pole 54. An exemplary support device 50 further includes a plurality of crossbars 60 and 62, and can include only a single crossbar. Each crossbar 60 and 62 has opposite ends that can be selectively positioned in any one of a pair of corresponding openings 58 in respective vertical poles 52 and 54.

Still referring to FIG. 4, an exemplary exercise method can be described using support device 50. An individual (not shown) can position one or more crossbar 60 in any one pair of corresponding openings 58 in respective vertical poles 52 and 54. Patterns of movement are represented as cones. Pattern cone 64 is associated with crossbar 60 and pattern cone 66 is associated with crossbar 62. Pattern cone 64 includes a circular outline 68 on substrate 56 and pattern cone 66 includes a circular outline 70 on substrate 56.

Still referring to FIG. 4, the exemplary exercise method includes the individual (not shown) using crossbar 60 of support device 50. The individual's hands could be generally positioned at point 72 of crossbar 60 of pattern cone 64 and the lower body of the individual could move in the circular outline 68 on substrate 56 via any one of the exemplary exercise devices disclosed throughout this document.

Still referring to FIG. 4, the exemplary exercise method includes the individual (not shown) using crossbar 62 of support device 50. The individual's hands could be generally positioned at point 74 of crossbar 62 of pattern cone 66 and the lower body of the individual could move in the circular outline 70 on substrate 56 via any one of the exemplary exercise devices disclosed throughout this document. Since crossbar 62 is elevationally lower than crossbar 60, the circular outline 70 of pattern cone 66 can have a greater diameter than circular outline 68 of pattern cone 64 for the same individual.

However, again referring to FIGS. 1-3, as the lower portion of the individual's body 18 moves for a greater distance from directly beneath the individual's 18 shoulders, stress in the joints and tissue of the lower leg area 17 (see FIGS. 2-3), including the knees and ankles, increases to compensate for the greater angle of the body from the vertical orientation of FIG. 1. The increased stress can led to catastrophic failure of one or more of the joints and tissue of the lower leg area 17 (FIGS. 2-3) including the knees and ankles.

Using the following inventive exercise systems and exercise devices can minimize the potential for this catastrophic failure to occur.

Referring to FIGS. 5-8, an exemplary exercise device 80 is illustrated and described. Exercise device 80 includes a pair of exercise structures 82 and 84 (body part retainer or body part securing device). One exercise structure 82 includes a foot retainer device for receiving, retaining and securing the right foot of an individual to the exercise device 80. The other exercise structure 84 includes a foot retainer device for receiving, retaining and securing the left foot of an individual to the exercise device 80. Each exemplary foot retainer device includes a sole (86 and 88 respectively) to support a foot and a strap configuration (90 and 92 respectively) to secure the foot to the sole (86 and 88 respectively). Collectively in this one example, the combination of sole and strap configuration establishes a sandal configuration.

Each strap configuration can be selectively opened and closed over a foot by a fastener such as a hook and loop fastener which would include a Velcro® configuration (which cannot be seen as such is located at the overlapping portions of respective straps). Additionally or alternatively, the straps can have openings (not shown) with shoe strings alternating through the openings for securing the foot to the sole. Each strap configuration can be a single integral structure without having a pair of discrete and overlapping structures. Still further, the strap configuration could be a string configuration alone such as shoe string. The sole can be made from metal, leather, wood, canvas, fabric, rubber, plastics, and other petrochemical-derived materials, or any combination of these materials. The strap can be made from leather, canvas, fabric, rubber, plastics, and other petrochemical-derived materials, or any combination of these materials. The strap configuration 90 and 92 can be secured or attached to the respective soles 86 and 88 or secured or attached to the platform 92 discussed more thoroughly below. Each strap configuration 90 and 92 can be secured or attached to the respective soles 86 and 88 and the platform 92.

It should be understood that an exemplary foot retainer device can include any one of the various different structures for an exemplary foot retainer device described throughout this document including, shoes, boots, sandals, string configurations, straps configurations, and any combination of these structures.

Still referring to FIGS. 5-8, each exercise structure 82 and 84 of the exemplary exercise device 80 includes a platform 92 (at least in this embodiment referred to as a first platform) that supports and secures the exemplary foot retainer device. The exemplary first platform 92 is generally planar having an upper surface opposite a lower surface and an outer side periphery having a circular configuration. The upper surface can be planar and smooth, can include ridges, can include any form of a rough, non-smooth surface, can include a perforated surface, can include a surface with divots, and any combination of these surface configurations. The outer side periphery can have any geometric periphery including a square, rectangle, oval, any parallelogram configuration, a diamond, any geometric configuration with 5 or more sides such as a hexagon, etc. The lower surface can have the same surface configuration as the upper surface, or a different surface and which includes any one or combination of the surfaces just described for the upper surface.

The foot retainer device and/or respective soles 86 and 88 can be secured or attached to the first platform 92 via glue, and/or via nut through sole and first platform, and/or via string over or through sole and into or through first platform 92, or any combination of these securement methods. It should be understood that any foot retainer device and/or sole described throughout this document can be secured in in the exercise device in any one of these securement methods.

Referring to FIG. 7, each exercise structure 82 and 84 of the exemplary exercise device 80 includes another platform 94 in this embodiment (for this embodiment referred to as a second platform 94 to distinguish from the first platform 92). First platform 92 and second platform 94 can be configured the same and include all of the different configurations and combinations of configurations just described with respect to first platform 92. Alternatively, the configuration of the first platform 92 can be different from the configuration for second platform 94. For example, the outer side periphery of one platform can have any geometric periphery different from the other platform, or the upper surface of one platform can have any different configuration relative the upper surface of the other platform, or the lower surface of one platform can have any different configuration relative the lower surface of the other platform, or any combination of the different upper, lower surface and outer side periphery.

Still referring to FIG. 7, the first and second platforms 92 and 94 rotate relative each other along a rotational axis generally along the bolt 81. An opening 87 extends through the first platform 92 to receive bolt 81 and a recess region 83 is established around opening 87 to receive the head portion of bolt 81. Bolt 81 extends through an opening 89 in at least one spacer or washer 85 and extends through an opening (under spacer 85) in second platform 94. More than one spacer or washer 85 can be positioned between first and second platforms 92 and 94 and on bolt 81, including two, three, four, five, and up to twenty, spacers or washers 85. At least one nut 91 is secured on the end of bolt 81 below second platform 94. Additionally, a second nut 93 and a washer 95 can be provided on on the bolt 81 below second platform 94.

Referring to FIG. 8, at least one ball, roller or wheel is rotationally and pivotally secured to the lower or bottom surface 97 of second platform 94 with an example being a swivel caster (or castor). For example, ball 96 is rotatably secured into pivot or swivel structure 98. Swivel structure 98 is capable of pivoting or swiveling on an axis generally perpendicular to second platform 94 and is secured to the bottom surface 97 via a bolt/nut combination 99. In this embodiment, five rotatable balls 96 are pivotably secured to the bottom surface 97 of the second platform 94. However, the exercise device 80 could have only three rotating and swiveling (pivoting) balls 96, or have only four up to 10 rotating and swiveling (pivoting) balls 96. While this embodiment of exercise device 80 has balls 96, each one or any combination of number could be a wheel structure, and each wheel structure could include a single wheel, include a double wheel or include a compound wheel.

While not shown, it should be understood that each of the at least one ball, roller or wheel 96 can include a brake feature (not shown) which prevents the at least one ball, roller or wheel 96 from rotating, a rotation lock. An exemplary brake feature (or rotation lock) includes a lever that presses a brake cam against the at least one ball, roller or wheel 96. A more complicated brake feature includes not only having the rotation lock, but further includes locking the swivel structure 98 to keep the wheel 96 from pivoting or swiveling, a swivel lock. It should be understood that the swivel lock and the rotation lock can be used independently, that is separately, or used together at the same time. In fact, if the swivel lock is engaged while the rotation lock is not engaged, the exercise device will move only in a single direction along a horizontal axis.

It should be further understood that if the exercise device 80 has two or more balls, rollers or wheels 96 (hereinafter wheel 96 for simplicity) there can be a rotation lock and/or a swivel lock for each wheel 96. Additionally, there can be a brake device that is capable of braking or locking all wheels 96 at the same time. Such an exemplary brake device can be configured having a rigid ring encircling, slightly above, each wheel 96 that lowers and presses down on the wheel 96 to preventing both rotation and swiveling of wheel 96.

Referring to FIGS. 9-12, an exemplary exercise device 180 includes a single structure supporting both foot retainer devices for each foot. Each foot retainer device includes respective soles 182 and 184 and respective strap devices 192 and 190. The exercise device 180 has a first platform 186 and a second platform 188. The exercise device 180 has rotatable rollers 194 in respective pivot or swivel structures 196 which are pivotably secured via bolt/nut combinations 181 to a bottom surface of second platform 188.

Referring to FIGS. 10-11, at least one bearing structure is secured between first and second platforms 186 and 188, respectively. In this embodiment, there are two bearing structures (second bearing 198 and first bearing 199). It should be understood that more than two bearing structures (such as 3, 4, 5, 6, 7, 8, 9, and 10 bearing structures) can be positioned between first and second platforms 186 and 188. Each of the bearing structures 198 and 199 are generally planar structures having an upper surface opposite a lower surface and an outer side periphery having a circular configuration. The upper and lower surfaces are generally planar and smooth. The outer side periphery can have any geometric periphery including a square, rectangle, oval, any parallelogram configuration, a diamond, any geometric configuration with 5 or more sides such as a hexagon, etc.

It should be understood that one bearing structure, or any combination of a number of bearing structures, can be configured as other bearing structures, such as ball bearing structures, for example, thrust ball bearing structures which include cylindrical thrust roller bearings structures, tapered roller thrust bearings structures, etc. Bearing structures configured not as ball bearing structures could replace any one or more of the bearing structures such as fluid bearing structures. If there are more than one bearing structure in an exercise device, all the bearing structures can be the same or the exercise device any have any different combination of bearing structures. Still further, any reference to a bearing or bearing structure throughout this document can be any one of these types of a bearing structures, or combination of bearing structures, just described.

It should be further understood that exercise device 180 could be devoid of any bearing structures similar to exercise device 80 of FIGS. 5-8. Moreover, each exercise structure 82 and 84 of exercise device 80 of FIGS. 5-8 could include one or more bearing structure similar to exercise device 180.

Still referring to FIG. 11, exercise device 180 includes a bolt 183 that is provided through an opening (not shown) in first platform 186 between soles 182 and 184, through opening 189 in first bearing 199, through opening 175 in second bearing 198, and through opening 191 of second platform 188. Bolt 183 is secured with at least one nut 167 adjacent a bottom surface of the second platform. Optionally, bolt 183 can be provided through opening 187 in one or more spacers (or washers) 185 between first platform 186 and first bearing 199. Optionally, bolt 183 can be provided through opening 173 in one or more spacers (or washers) 171 between first bearing 199 and second bearing 198. Optionally, bolt 183 can be provided through opening 179 in one or more spacers (or washers) 177 between second platform 188 and second bearing 198. Optionally, bolt 183 can be provided through opening 195 in one or more spacers (or washers) 193 between second platform 188 and nut 169. It should be understood that more than one spacer can be provided between the platforms and bearings. Additionally, more than one nut can be provided to secure bolt 183 such as nut 167.

Referring to FIG. 12, the lowermost surface 163 of exercise device 180, and second platform 188, is shown.

Referring to FIGS. 13-15, exemplary exercise device 110 is illustrated and described. Exercise device 110 includes foot retainer device 111 having at least one strap 112 (two straps shown) and sole 113. Foot retainer device 111 is secured to first platform 114, first platform 114 is secured to bearing 115, bearing 115 is secured to second platform 123, second platform 123 is secured to pivot/swivel device 124, pivot/swivel device 124 is secured to third platform 117, third platform 117 is pivotably secured to a plurality of wheel swivels 118 which are secured to wheels 119 in a rotationally relationship. A foam structure 116 is provided between second platform 123 and third platform 117 and acts as a shock absorber and support between second platform 123 and third platform 117. The foam structure 116 has a slit 243 to provide the capability for the foam structure to be selectively spread open so that the foam structure 116 can be selectively removed from, and selectively positioned between, second platform 123 and third platform 117. This allows for access to pivot/swivel device 124 and allows for replacing foam structure 116 with a different material or composition or to replace foam structure 116 with a completely different structure. Alternatively, the foam structure 116 does not have the slit 243.

Referring to FIG. 15, foot retainer devices 111 are secured to first platform 114 in a stationary relationship. Alternatively, each foot retainer device 111 is secured in a pivoting relationship with the first platform 114 via a pivot pin or bolt (not shown) which extends through each sole 113 and into at least a portion of first platform 114. A bolt 127 is secured in second platform 123 and extends through bearing 115 and first platform 114 and is secured to first platform 114 via spacer 126 (or washer) and nut 125. The first and second platforms 114 and 115 are capable of rotating relative to each other with bearing 115 there between, and the rotation axis is defined along bolt 127.

Referring to FIGS. 13-15, pivot/swivel device 124 includes two brackets 125 (only shown), a hinge 130 and a support/spacer 128. Hinge 130 includes a pivot 135 (pixot axis extends horizontally across page and parallel with third platform 117) between an upper flange 218 (triangularly shaped) and a lower flange 234 (extending perpendicularly to upper flange 218). Each bracket 125 has a right-angled configuration with a horizontal portion 127 extending perpendicularly from a vertical portion 126. Two bolts 140 and respective nuts 120 secure the horizontal portion 127 of each bracket 125 to second platform 123. The two brackets 125 are spaced from each other to allow an upper portion of upper flange 218 of the hinge 130 and an upper portion of support/spacer 128 to be positioned between the vertical portions 126 of brackets 125. An opening 228 in each of the vertical portions 126 of the two brackets 125 is aligned with opening 318 (see FIG. 15) in the upper portion of the upper flange 218 of the hinge 130 and aligned with an opening (not shown) in the upper portion of the support/spacer 128. Pivot pin 242 (FIG. 14) extends through the respective openings of the two brackets 125, hinge 130 and support/spacer 128 and a washer (not shown) and nut 238 (not shown) to secure pivot pin 242 in place. The pivot axis is defined by pivot pin 242 and extends perpendicularly to the vertical portion 126 of bracket 125 and page. Accordingly, bracket 125 rotates around or about pivot pin 242 which is oriented perpendicularly to pivot 135.

Referring to FIG. 14, this cooperation of pivot pin 242 allows for first and second platforms 114 and 123 (including brackets 125) to pivot about an axis that is perpendicular to the page in the view of FIG. 14. For example, if a force 122 is directed downwardly on one foot retainer device 111 and is greater than a force 121 directed downwardly on the other foot retainer device 111, the foot retainer devices will pivot in a clockwise direction 223 (from this view of FIG. 14). It should be understood that the foot retainer devices are capable of pivoting in the opposite direction (relative to direction 223) in a counterclockwise direction. Additionally, pivot 135 allows for the first and second platforms 114 and 123 (including brackets 125) to pivot about an axis that is horizontal across the page in the view of FIG. 14. The lower flange 234 of hinge 130 is secured to third platform 117 via bolts 233 and nuts 225.

Referring to FIGS. 16-18, an exemplary exercise device 260 is illustrated and includes a base 269 (or first platform) supported upon a plurality of wheels 270. Wheels 270 can be swivel wheels 270 (i.e., caster wheels 270) or can be stationary and configured in a specific linear direction. An opposite side of base 269 from wheels 270 includes an axle device 266 having a flange 264. Axle device 266 is secured to an upper surface of the base 269 in a rotational or pivoting relationship via braces 267 over opposite ends of the axle device 266. The pivotal relationship allows the flange 264 to rotate approximately 180 degrees in direction 268.

Still referring to FIGS. 16-18, a foot platform 262 is pivotally secured to the flange 264 of axle device 266 via pivot pin 265 which allows the foot platform 262 to pivot in direction 261. Outlines of feet 263 demonstrate where feet would be placed and secured to foot platform 262 of exercise device 260. Referring to FIG. 17, feet 263 are secured to the foot platform 262 by straps 271. The rotational axis defined by the axle device 266 is perpendicular to the rotational axis defined by pivot pin 265.

Referring to FIGS. 19-20, an exemplary exercise device 280 is illustrated and includes a base 286 (or first platform) supported upon a plurality of wheels 289. Base 286 is generally rectangular-shaped (but could be any geometric configuration) and includes lifters or spacers 287 at opposite edges of the base 286. Each lifter 287 includes a notch 288. Exercise device 280 further includes a foot platform 281 having an axle 284 secured or anchored (affixed) to a side of the foot platform 281 opposite an upper side 282. Axle 284 is secured by clamps 283. Axle 284 extends the length of foot platform 281 and has opposite ends extending past opposite edges of the foot platform 281 in an exposed fashion. The exposed opposite ends of axle 284 are to be positioned in the notches 288 of the lifters 287 wherein foot platform 281 has the capability for rotation in direction 285 relative to base 286 about an axis defined by axle 284. Foot platform 281 is elevetionally spaced above base 286 in the rotational relationship 285.

Referring to FIG. 20, braces 289 over notches 288 (and ultimately over exposed ends of axle 284) will maintain axle 284 and foot platform 281 positioned relative to base 286 in the rotational relationship 285. It should be noted that in this FIG. 20) the length of lifters 287 extend generally the entire width of base 286. Alternatively, referring to FIG. 19, the length of lifters 287 extends only a portion of the width of base 286.

Referring to FIG. 21, an exemplary exercise device 300 is illustrated and includes a base 301 (or first platform) and in this view only a bottom surface of base 301 is shown.

Contacting the circular pods 665 will register the “points,” represented by the numerical value in the respective circular pods 665. As various ones of the plurality of circular pods 665 are contacted, pressure upon each circular pod 665 from the weight of the individual 669 creates an electrical connection which is indicated on laptop 663 and/or screen 664 as the corresponding numerical value listed.

Still referring to FIGS. 40A-B, and in one exemplary embodiment, the ultimate goal can be to score as many points as possible in a given time frame to “win” the game. Accordingly, the numerical values in the circular pods 665 can be selected to encourage the individual 669 to move in a certain way, for example, in circles, with the assumption that the individual 669 will desire to acquire the greatest total of pod values in the shortest time period. Additionally, the circular pods 665 which are the farthest removed from the central circle 675 can be selected to have the greatest numerical value to encourage the individual 669 to desire to contact these circular pods 665, again with the assumption that the individual 669 will desire to acquire the greatest total of pod values in the shortest time period. In this way, the difficulty of the game increases as the contestant attempts to contact the circular pods 665 with the larger numerical values to win the game, and correspondingly, increases the difficulty of reaching the circular pods 665 with the greater numerical value which increases the health benefit of the game for the individual 669.
